a trial of lenvatinib (e7080) plus pembrolizumab in participants with selected solid tumors

Conditions: Tumors

Summary: this is an open-label phase 1b/2 trial of lenvatinib (e7080) plus pembrolizumab in participants with selected solid tumors. phase 1b will determine and confirm the maximum tolerated dose (mtd) for lenvatinib in combination with 200 milligrams (mg) (intravenous \[iv\], every 3 weeks \[q3w\]) pembrolizumab in participants with selected solid tumors (i.e. non-small cell lung cancer, renal cell carcinoma, endometrial carcinoma, urothelial carcinoma, squamous cell carcinoma of the head and neck, melanoma or leiomyosarcoma). phase 2 (expansion) will evaluate the safety and efficacy of the combination in 7 cohorts at the mtd from phase 1b (lenvatinib 20 mg/day orally + pembrolizumab 200 mg q3w, iv).


Eligibility criteria:
inclusion criteria: 1. phase 1b: histologically and/or cytologically confirmed metastatic selected solid tumor types that have progressed after treatment with approved therapies or for which there are no standard effective therapies available. if nivolumab or pembrolizumab is an approved therapy for the participant's tumor type, but the participant has not been treated with it, the investigator may enroll the participant in this study. phase 2: histologically and/or cytologically confirmed metastatic selected solid tumor types with 0-2 prior lines of systemic therapy. if previously treated, participant has progressed after previous treatment. for the non-small cell lung cancer (nsclc) and melanoma cohorts, participants must have progressed on or after prior treatment with one anti-programmed cell death protein 1 (anti-pd-1), anti-pd-1 ligand 1 (anti-pd-l1), or anti-pd-1 ligand 2 (anti-pd-l2) agent. for the renal cell carcinoma (rcc) cohort, participants must have progressed on treatment with an anti- programmed death receptor-1 /programmed death receptor-ligand 1 monoclonal antibody (anti-pd-1/pd-l1 mab) administered either as monotherapy, or in combination with other checkpoint inhibitors or other therapies, the regimen with an anti-pd-1/pd-l1 mab must be the most recent therapy. selected tumor types of both phases: nsclc, predominantly clear cell renal
